I’ve a suggestion for a new ability…it would be be somewhat like spear wall, but with the aim of protecting one of your other brothers. You’d select a neighbouring battle brother to protect, and then any enemy attacks against that brother (that are in the attack range of the protector) have a chance to be interrupted/intercepted, hitting the attacker (like spear wall does). Probably the ability would have a corresponding penalty to the protector’s own defence.
It could have come in handy to protect Kurt (in the EA “Let’s Play”, ep. 4)! You could call it something like “Protector”, or “Guardian Angel”, or “Bodyguard”.
